CAMP

Application filed September To a/ZZ whom it may concern.

Be it known that we, Louis B. Gonnnnnc. NATHAN GOLDBERG, IVILLIAM Geronimo. and Jason M. GOLDBERG. citizens of the Jnited States, residing at Denver, county of Denver, and State of Colorado, have invented certain new and useful Improvements in Camp Stoves; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the char acters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in gasoline stoves and has particular reference to that type of stove generally referred to as camp stoves. Y

The advent of the automobile has ushered in an era of roving which has developed to such an extent that a considerable proportion of our population is constantly on the move during the summer months. In order to become independent of the hotels, it is customary for people traveling with automobiles to carry camping equipment, including cooking utensils. To obviate the necessity of building wood fires and to enable cooking to be done when wood is unavailable, it has been proposed that compact gasoline stoves be carried, and many different stoves have been invented for this purpose.

It is the object of this invention to improve the construction of this type of stove so as to overcome certain objections and there by to produce a stove that shall be more satisfactory than similar stoves now on the market.

In order to better and more clearly describe our invention, we shall have reference to the accompanying drawing in which the preferred form thereof is shown, and in which:

The same reference cl'iaracteii's will be employed to designate the same parts throughout the several views. I

Numeral 1 represents a rectangular box which has a cover 2 hinged to the upper edge of one side thereof and which forms a carrying case and may also be considered as the stove frame. The burners or the stove proper consists of a central tubular member 3 whose ends are closed by cup-shaped plugs 4 antogenously welded thereto. At a point 5, substantially midway between the ends of member 3, is a vapor-receiving chamber 6, one end of which is welded to the opening in tube 3 and the other end of which extends parallel to the same. A plate 7 closes the end of member 6. This plate has an opening for the reception of the fuel supply pipe 8 which extends from the fuel reservoir 9 and is provided with a control valve 10. Plate 7 also has a cuplike portion 11 which receives and holds a small amount of gasoline, by the combustion of which the pipe 8 is heated sufliciently to convert the gasoline therein into vapor which then passes into the vapor chamber 6 and into the interior of tubular member 8. The gases which leave the end of pipe 8 with considerable force, cause air to enter through the open end 12 and to be added thereto in sufficient quantity to form a combustible mixture. At each end of memher 3 there is located a burner consisting of a funnel-shaped, pressed steel member 13 whose narrow end is welded or otherwise secured .to the sides of opening 14. inpipe 3. The wide end of the funnel has its edges 15 bent upwardly so as to form a seat for the burner 16. The tubular member 3 is supported by an lift-shaped bracket having vertical sides 17 terminating in feet 18 which are perforated for the reception of screws 19 which have thread connection with lugs 20 ongrate 21. The grate has feet 22 that rest upon the upper surface of the burner 16 and in combination with the screws 19, holds the parts in place. The tubular member rests in the bottom of the notch 23. A strap 24 has its center perforated and lies between the upper surface of the tubular member 3 and the bottom of the funnel.shaped memher 13. The ends of the strap have lugs which can be bent about the strap 1'? in the manner shown most clearly in Fig. The action ot the strap 24 is to hold the tubular member against any rotary movement.

As it is desirable to have at least two burners and as it is often unnecessary to use more than one, it is necessary to provide a valve mechanism by means of which the burners that are not needed can be closed off and when in use can be regulated. Our valve means comprise a plunger 26, shown in elevation in Fig. 4. This plunger has a central stem 27, to the upper end of which is secured a part having tapering sides 28. to the lower edge of which are attached downwardly projecting lugs 29 which serve as guides. The tubular member 3 and the supporting bracket 17 are perforated for the reception of the stem 27 which has a diametrical opening 30 near its lower end. The plunger 26 can move to open, dotted line position, 3, or to closed full line position and may occupy any intermediate position. The means for controlling the position of the plunger consists of a rod 31 whose end 32 projects through a hole in one or" the vertical legs of the bracket 17. Rod 31. also passes through the opening 30 and has its other end cooperatively connected to the end of the crank arm 33 of rod 34. Rod 3% is journaled in suitable openings in the ends of supporting member 35. A spring 36 surrounds the rod and serves to spread the ends of the bracket 35 apart so as to produce sufficient friction to hold the rod from rotating of its own accord. It will also be noted that the spring 36 fits the rod 34; snugly at one end so as to cause considerable friction when there is relative rotation between the spring and rod. A tubular member 37 has a head 38 and a longitudinal slot 39. A pin 40 secured to the rod 34; projects through slot 39 and prevents relative rotation while permitting a limited longitudinal movement. The object of the telescopic arrangement between rod 3 and the tubular shank 37 is to permit the valve handle to be pulled out into the position shown in Fig. 1. or pushed back into "the cas mg so as to prevent it from becoming bent or broken. p

The tubular member 3 is of a special construction which is of very light weight and of great strength, being formed of two substantially identical semi-cylindrical sections which I have designated as a and 7). These sections have cooperating flanges c which are autogenously welded. The ends are closed by cup-shaped members 4, also welded to the ends ofthe tubular member. The vapor receiving chamber 6 is formed of two supplementary parts welded together at d and is welded to the tubular meniber3. The construction just described produces an element having all of the advantages of a heavy cast-iron piece and only a small part of the latters weight, which is an item of considerable importance in a portable stove.

Another advantage of the light-weight construction of the tubular member 3 is that it heats up very readily and thereby makes it easier to start the stove, as well as improving the operation after it has started.

Attention is called to the fact that when the rod 3% is rotated, for the purpose of operating the valve. the lever 81, owing to its crooked shape and to the fact that it passes through a hole in the end 01" the stem and through another hole in the bracket will be caused to rotate. The bent end will engage the foot 18, when the valve is fully open, and act as a stop.

The store described above operates in the same manner as ordinary stoves of this type. The gasoline is containedin an air-tight cylindrical reservoir 9 into which air is also forced. The pressure of the air tends to force the gasoline out through the pipe 8 which passes over one of the burners and projects into the vapor-receiving chamber. To start the stove, a small quantity of gasoline is placed in the cup 11 and ignited. This heats the gasoline in pipe 8 and converts it into a gas which mixes with air in the receiving chamber 6 and flows from thence to the burner 13 where it burns and keeps pipe 8 hot. If more than one burner is needed. the knob 38 is turned and this opens the valve, permitting gasto flow out and by adj Listing valve 10 the volume of gas genera-ted can be regulated.
